Cant unlink a curve created from an instanced collection
Found this unanswered question as I was facing the exact same problem -- I solved it with this:
In Object Mode, select all objects that you want to be separated. When I &quot;made instances real&quot; I was able to select them individually in Object Mode, but they would all edit together in Edit Mode.
Use the Object dropdown menu &gt; Relations &gt; Make Single User &gt; Object &amp; Data.
I did not unlink my textures, as I wanted them to remain uniform for the time being. This will make every selected object an individual editable object. This was enough for my own problem.
If you want to regroup objects -- perhaps all the objects on the right side -- Select them in Object Mode, Object dropdown &gt; Relations &gt; Make Local &gt; Selected Objects and Data. This somehow relinks them, but not vertex to vertex as they were before. I haven't been able to find the solution to this second half of the problem.
For further clarification on what this is doing, look up &quot;Make Single User&quot; and &quot;Data Blocks&quot;. I'd explain it here if I fully understood it myself.
Hope this helps some!
